CHARLES LISS, OF NEW YORK, N. Y.

OVERFLOW-ALARM.

SPECIFICATION forming part of Letters Patent No. 620,713, dated March '7, 1899.

Application filed December 28,1898. Serial No. 700,485. (No model.)

To all whom, t may concern.:

Be it known that'I, CHARLES LIss, a citizen of Germany, and a resident of New York, (Brooklym) county of Kings,and State of New York, have invented new and useful Improvem ents in Overflow-Alarms, of which the following is a specification.

This invention relates to an electric overflow-alarm for refrigerators and similar articles iu which the alarm-box is removably attached to the drip-pan by means of a frame of peculiar construction, which also constitutes a support for the actuating-lever that sets the alarm olf. y

In the accompanying drawings, Figure lis a Vertical section of my improved overliowalarm on line 1 l, Fig. 2. Fig. 2 is a plan thereof, and Fig. 3 a-detail perspective view of the frame d.

, The letter d represents a frame adapted to straddle the wall of the drip-pan A of a refrigerator, rbc., and to removably support an alarm-box B of conventional construction.

The frame d, as illustrated in Fig. 3, is

composed of a continuous bar or Wire, the

Shanks of which extend downward, as at d', and then upward, as at a2. Thus upper hooks as are formed that are adapted to engage the pan A, while the lower hooks a2 grasp one of the sides of the box B, and thus hold such box tightly against one side of the pan, Fig. l.

The box B is provided with a dry battery i), electromagnets, (in case b,) gong b2, clapper b3, spring-contacts h4 h4, and the circuitwires, which when contact is established close the circuit to set oif the alarm.

Above the upper bend a3 of frame d are formed a pair of bearings d4, in which turns a longitudinal shaft c. To this shaft there is affixed a lever c', having its shorter downwardly-bent arm c2 placed vertically above and between the contacts b4. This arm is guided in its vertical movement by a U -shaped guard e, projecting upwardly from box B. The longer lever-arm projects partially across pan A and carries a suitable iioat d by means of a suspending-rod d.

In use the frame d is set to straddle the pan A, and then the box Bis hooked into the frame, so that in this way the parts are assembled in a simple manner. The drip-water upon accumulating will gradually raise the lioat, which will in turn swing the lever d. When the danger-point has been reached by the drip-Water, the lever-arm c2 will enter between and connect the two contacts b4 to` close the circuit and sound the alarm. lWhen the water has been poured out, the float will fall to raise the lever-arm c2, break the Contact, and stop the alarm.

It will be seen that by my invention an alarm-box maybe operatively secured to overiiow-basins in a simple and reliable manner and Without requiring any iittiug or skilled adjustment.

What I claim is@ 1. A frame for overlioW-alarms having au upper hook adapted to straddle the drip-pan,

fied.
